Abdominal Aortic Aneurysm (AAA)

An abdominal aortic aneurysm is an enlargement of the aorta that forms in the abdomen as a result of a breakdown in the strength of the aortic wall causing a ballooning of the aorta. While all the causes are not well understood, hypertension, high blood pressure, smoking, and family history play a role in aortic disease and may result in aneurysms, dissection or rupture of the aorta.

Signs and Symptoms

Many patients with abdominal aortic aneurysms do not experience any symptoms.
